Description

Technical Field

[0001] The utility model belongs to the technical field of louvered hollow glass, and particularly relates to the improvement of electric built-in louvered hollow glass blades. Background Art

[0002] Electric blinds use DC motors to drive the blades up and down instead of the traditional hand-pulled transmission method of blinds. They have the function of automatically flipping the curtain blades, which can effectively block direct sunlight and adjust the indoor light. Therefore, they are widely used in office buildings, conference rooms, stadiums, family homes, hotels and other places.

[0003] The existing electric blinds and insulating glass have the following problems in actual use: in order to ensure that the blades can be flipped normally, gaps are set between the blades. In addition, the shape of the blinds is curved, so after the blades are flipped and in the shading state, there will still be certain gaps between the blades, which cannot achieve complete shading and cannot meet the use requirements of some places that require high shading. Moreover, at certain angles, the indoor conditions can still be observed from the outside, which cannot meet customers' increasingly high demands for privacy protection.

[0004] The slats of Venetian blinds for insulating glass with built-in blinds in existing technologies, including those disclosed in patents for insulating glass with built-in blinds, have a generally semicircular cross-sectional shape. Consequently, even when the slats are adjusted to their maximum closed position using an adjustment mechanism (commonly referred to in the industry as a "slat flip adjustment control mechanism"), a significant gap, approximately 3.5-4 mm wide, remains between adjacent slats. Consequently, when the Venetian blind is closed, it cannot provide 100% light blocking. While one design approach could mitigate this limitation by reducing the spacing between adjacent slats, this has proven undesirable in practice. Excessively increasing the number of slats can significantly reduce lighting performance, create interference between adjacent slats, increase manufacturing costs, waste resources, and violate design specifications and relevant standards.

[0005] Therefore, it is urgent to design a blade for a built-in blind insulating glass that can completely block light. Utility Model Content

[0006] In response to the above technical problems, the utility model provides fully shading electric built-in blinds insulating glass to meet the user's needs for full shading and privacy protection.

[0007] The technical solution of the utility model is: a fully shading electric built-in blinds insulating glass, comprising a window body, a blind, a transmission shaft, a plurality of rope winders, a flip seat and an electric mechanism, wherein the blind is arranged in the glass cavity of the window body, the transmission shaft, the rope winder, the plurality of flip seats and the electric mechanism are all arranged in the upper frame of the window, one end of the transmission shaft is connected to the electric mechanism, and the other end of the transmission shaft is connected to the rope winder and the flip seat, the rope winder controls the raising and lowering of the blind by retracting and releasing the lifting rope, and the flip seat controls the flipping of the blind by rotating the flip ladder rope.

[0008] The venetian blind is composed of a plurality of blades, each of which includes a blade body, an upper bending portion and a lower bending portion, and the straight-line distance from the upper edge of the upper bending portion to the lower edge of the lower bending portion is adapted to the length of the ladder rope between the turning ladder ropes;

[0009] The angle between the blade body and the upper bent portion is the upper angle, and the angle between the blade body and the lower bent portion is the lower angle. Both the upper angle and the lower angle are obtuse angles exceeding 100 degrees, and the upper angle is greater than the lower angle.

[0010] The length of the blade body is L1, the length of the upper bending portion is L2, and the length of the lower bending portion is L3, wherein L1>L2>L3;

[0012] Preferably, the center of gravity of the blade is located at a middle position when the blade is placed horizontally on the ladder rope.

[0013] Preferably, the electric mechanism further includes a wireless control device.

[0014] Preferably, the upper frame includes a top frame strip, an upper frame cover plate and a spacer strip;

[0015] The upper frame strip is provided with an upper frame strip cavity, and the upper frame strip top plate and the upper frame strip bottom plate are provided on the upper and lower parts of the upper frame strip cavity, respectively.

[0036] The Venetian blinds 2 are located within the glass cavity of the window 1. The drive shaft 3, cord winder 4, two flip seats 5, and motor 6 are all located within the upper frame of the window 1. One end of the drive shaft 3 is connected to the motor 6, which is then connected to the mains electricity. A limiter 7 is also provided on the drive shaft 3. The limiter 7 is a conventional component used to control the end point of the Venetian blind's lifting and lowering.

The other end of the drive shaft 3 is connected to the cord winder 4 and flip seat 5. The cord winder 4 controls the raising and lowering of the Venetian blinds 2 by retracting and releasing the lifting cord 41.

Both the upper angle and the lower angle are obtuse angles exceeding 100 degrees, and the angle of the upper angle is greater than the lower angle. In this embodiment, the upper angle is selected from 140 to 165 degrees, and the lower angle is selected from 100 to 135 degrees.

[0040] The length of the blade body is L1, the length of the upper bend portion 212 is L2, and the length of the lower bend portion 213 is L3. In this embodiment, the length of L2 is selected to be 1 / 3 to 1 / 2 of L1, and the length of L3 is selected to be 1 / 6 to 1 / 4 of L1. For example, the length of L2 can be selected to be 1 / 3 of L1, and the length of L3 can be selected to be 1 / 5 of L1.

The left and right side frames 12 and 13 have the same structure, and the ends of the Venetian blind 2 extend into the side frame cavities of the left and right frames 12 and 13. This prevents the blades 21 from scraping against the inner surface of the glass when the Venetian blind 2 is opened, closed, flipped, or raised.
